The ARGoS Forum

hi carlo,

Thank you very much for the explanation. i have a clearer picture of how argos works, at the same time i will like to seek your advice on segmentation fault. I'm hitting this fault, the program was initialize with no problem but the moment i press the start button the program will exit and display "segmentation fault". no error during the compilation. any advice on this?

Thank you
Regards
Max

Hi Max,

Segmentation faults are the most common run-time errors when programming in C or C++. It means that you have errors with the management of the memory. It could be literally anything - from a pointer used without initialization, to more complex problems.

To debug a segfault you need to learn how to use a debugger. Depending on your platform, you would use gdb or lldb.

Also, you need to compile your code with debugging symbols. To do this, assuming you're using the ARGoS examples as a base, you should run the command
in your build directory.

If you're a beginner, I strongly advice you to refer to a friend/colleague who can help you through the debugging process, at least the first time.

Cheers,
Carlo

Thank you Carlo for the clear explanation on how to carried out debugging.
